AITAH for not being as attracted to my gf after seeing her baby photos?

I recently moved in with my girlfriend to a prefurnished apartment that I specifically picked out because the place was already decorated in a way that made me feel at home. Probably a hot take but I hate the labor involved with acquiring new furniture and art work to transform an empty box into my den. I’d rather that already be done. I thought my girlfriend felt the same way, but a couple weeks after we moved in she started changing things. For example, I came home from work one day and the dining room chairs were changed. That didn’t bother me at all, because I wasn’t doing the work, and hey, if the interior deco shit brings her joy, I’m all for it.

But then, the art work over the fireplace was replaced by the 5x10ft portrait of a baby that, let’s just say, looked disformed and malnourished. I asked my girlfriend about it and she said it was a painting her parents had sent us that they had made, which depicted her as she was a few days after arriving home from the hospital. I thought the art style was a bit ugly, but I held my tongue. My girlfriend is very attractive so I figured the artist was just a poor painter.

Then she started to hang up actual photos of her as a baby and turns out the artist was pretty spot on. My girlfriend was one of the ugliest babies I’ve ever seen. She had a huge dented head and her eyes were different shapes and sizes.

Basically all the art work has been replaced by huge photos of her as a baby and one sonogram in the bathroom and the place I call home is now filled with these images I don’t like looking at. And now when I look at my girlfriend, who let me be clear is so out of my league it’s not funny— my friends say I got beyond lucky— I see the baby. I can kind of see the head dent and that her eyes are indeed different sizes. It’s not something I would have noticed before, but now it’s all I see.

She’s noticed that I kind of avoid eye contact with her now and that I stay in the one corner of our apartment without any baby photos and is asking what my deal is. I don’t want to tell her the truth as it would destroy her, but I’m simply not attracted to her anymore.

Am I a dick? I feel horrible for having these thoughts but it’s ruining critical parts of my life, my relationship and my ability to relax at home, and I just don’t know what to do.
